The Kauwgombol (chewing gum ball in English). This ball is actually a globe attached to a lamp-post and you're encouraged to stick your flavourless chewed up gum on it, maybe on the country you are from or any other country if you fancy it. Slowly I would assume the ball will get covered in gum and replaced with a new one. Could be quite gross in the summer with a load of flies settling down for a chew though couldn't it?!
